I am trying to convert Celsius to Fahrenheit in the following code. As you can see I have tried various ways. Get one working and the other wont work. What am I missing in the print statement. Thanks for the help.
import dht
import machine
import time
print('Starting DHT11.')
d = dht.DHT11(machine.Pin(4))
#temp = (d.temperature()*(9/5)) + 32 # eg. 23 (°C)
#humid = d.humidity() # eg. 41 (% RH)
while True:
print("Measuring.")
retry = 0
while retry < 3:
try:
d.measure()
break
except:
retry + retry + 1
print(".", end="")
print("")
if retry < 3:
#print('Temperature: ' + str(temp) + '°F, Humidity: ' + str(humid) + '%')
#print((d.temperature()-32)*(5/9))
print(" Temperature: %3.1f %% Fahrenheit" % d.temperature())
print(" Humidity: %3.1f %% Relative Humidity" % d.humidity())
time.sleep(5)
#temp = (d.temperature()*(9/5)) + 32

Hello, you can use the example that we have in the “MicroPython eBook” for the ESP DHT Web Server example: https://github.com/RuiSantosdotme/ESP-MicroPython/blob/master/code/WiFi/Web_Server_DHT/main.py
Basically, you just need to do this:
sensor.measure() temp = sensor.temperature() #converts temperature to Fahrenheit temp = temp * (9/5) + 32.0
I know this code works to convert it from Celsius to Fahrenheit
